Dampening the core one
Hi , I am thinking how to „stack“ the core one?
printer- squashballfeet-concrete tile- foam
ore : printer-supplied rubber feet- tile- squashballfeet
what do you guys think would be best. ?
RE: Dampening the core one
I'm using: printer - stock rubber feet - granite tile (40x40) - foam.
Gyroid can become a bit funny, when the printer is shaking quite a bit, but the print quality is better, than when standing on the rubber feet on the concrete floor.

Presumably Prusa has some of these in their farm now - any idea if they have additional damping they use?

Massive steel plate, printed short feet, TPU pads... works really well
RE: Dampening the core one
I have used surplus 60x60cm floor tiles and dampening materials in different thickness from the local dyi store. Four layers of tiles seem to do the trick it now sits on a wall mounted desk and the desk is more or less stable during print, only small movements can be felt transfer to the desk. The floor tiles are about 20kg each, the local floor tiling supply had some left over not in inventory that they where nice enough to cut down in size to match the printer for some fika bread.

I have mine on a rubber playground tile.

Done something similar, placed it on a 40x40 concrete tile + gym mat (the interlocking type, not very thick).
Have you tried to run the input shaper calibration before and after? I've gotten similar values for the X axis (MZV 47Hz) but pretty different values for the Y axis (before: MZV 47Hz, after: ZVD 53Hz). The ZVD here means that the peak isn't as narrow, but without being able to look at the graphs it's hard to judge.
Either way, the prints are much better than when placed directly on the gym mat and I can't see any ringing.
RE:
I am using printer | granite tile | carpet | floor. I am also consider 'taming' the profile I am using, some of the accelerations are too aggressive for my test.
As opposed to the Voron 2.4. the X/Y is at the top and thus creates more vibrations.

What is your aim, to lower noise? I've got squash ball feet on my MK4 and the difference in noise is HUGE. I can't recommend it enough. I installed them early on in my 3D printing journey so I didn't have enough experience to reliably assess print quality with and without the squash ball feet, but when assessing now I don't think they're do any harm at all to the print quality.

I’ve never been a big fan of the Prusa feet. My mk3s and mini+ both have had the stock feet replaced with these Sorbothane hemispheres. They do phenomenal job. All of my printers sit on a very heavy coffee table in the corner of my office. I’ll be replacing the feet on my Core One as soon as Amazon makes its delivery today.

The 1.75 inch 50 durometer version is currently on sale for $19.99 American.

RE: Dampening the core one
I used the squash ball feet edited to fill the ball holes solid, sitting on 5mm gyroid TPU pads. The entire printer is on a 35lb porcelain slab, sitting on a dedicated oak cabinet, That cabinet sits on engineered oak hardwood flooring glued to the concrete foundation of my house.
It's not moving.
